Hello,
Just to add a quick note.. It is possible to obtain the 14 digit serial number on
some radios with .
Use either the Measuring Value Block Group [081] Advanced Control Module Identification
or
Select
[Advanced ID-1A] (if applicable)
Some Audi and VW test plans still may use the manual entry of the serial number for older radios and
this way you do not have to pull the radio to 'see' the etched serial number on the radio.
Not that this helps, but that was one of the many, many time saving uses I found for when I was at the dealer, work smarter, not harder,
